GREEN BAY -- The Green Bay Packers may not go with rookie seventh-round pick Matt Flynn as their No. 2 quarterback behind Aaron Rodgers -- despite him being significantly more productive than rookie second-round pick Brian Brohm during the preseason -- but give the kid this much: He makes plays.

Flynn nearly pulled off an epic comeback during the Packers' 23-21 preseason-

ending loss to the Tennessee Titans Thursday night at Lambeau Field, rallying his team from a 23-7 deficit with a pair of touchdown passes, including a 22-yarder as time expired that left the Packers within a 2-point conversion of forcing overtime.

Was it enough to overtake Brohm and keep the Packers from adding a veteran backup?

"I'm not looking at that. The coaches have to make those decisions," said Flynn, who finished the preseason having completed 27 of 42 passes (64.3 percent) for 209 yards, with three touchdowns and no interceptions for a 100.2 rating. "All I can do is control how I play out there."

Under heavy rush much of the night and alternating every two series, Flynn was 8-for-13 for 77 yards in five series, while Brohm was 7-for-12 for 52 yards and a 68.8 rating in six full series.

Flynn hit Brett Swain for a 6-yard touchdown on a slant pass late in the third quarter, and on the last-gasp comeback drive, he had a huge play with a 20-yard fourth-down completion to Joey Haynos and a 21-yard third-down scramble before his TD throw to Jake Allen.

Asked if he would concede that Flynn deserves the No. 2 job, offensive coordinator Joe Philbin replied, "I wouldn't concede anything at this point. We haven't really had those discussions."

Brohm finally had something good happen when, on fourth-and-15, he scrambled and threw a 27-yard touchdown pass to Allen with 4 minutes, 6 seconds left in the game. But even that turned out poorly, as the Titans challenged the call and the replay showed that Allen did not maintain possession of the ball and the touchdown was overturned.

"Anytime you're out there, you're trying to show what you can do and show you're capable of doing the job," said Brohm, who was 19-for-42 (45.2 percent) for 155 yards, with no touchdowns, one interception and a 45.2 rating. "I felt pretty good overall."

Jansen injured

The Packers could be in the market for a long-snapper after rookie J.J. Jansen suffered a left knee injury during the fourth quarter. Coach Mike McCarthy didn't know the severity of the injury after the game.

Jansen was injured after releasing a high snap on a punt, which punter Jon Ryan improvised into a 34-yard run. That ended a rough night during which Jansen also had a low snap on the extra point after the Packers' first touchdown.

"When he came off the field hobbling, I said, 'How's your knee?' He said, Not good,' " special teams coordinator Mike Stock said. "Right now, we'll just wait and see."

Jansen, an undrafted rookie from Notre Dame, won the long-snapping job from Thomas Gafford, who was released early in camp when halfback Ryan Grant came to terms. The Packers are replacing retired Rob Davis, who moved into the front office and by NFL rule cannot unretire and join the team as a player because the deadline for returning while working for the club in another capacity has passed.

Linebackers shine

If starting middle linebacker Nick Barnett has any say, the Packers will keep backup linebackers Abdul Hodge, Desmond Bishop and Tracy White. Hodge (nine tackles), Bishop (nine) and White (seven) finished 1-2-3 in tackles Thursday night. All three made big plays on the three series immediately after the starters departed. In addition, Spencer Havner made a pair of nice tackles on special teams to make his case for a roster spot.

"I think we need to keep seven linebackers this year," Barnett said.

Line competition

With center Scott Wells (back) and rookie right guard Josh Sitton (knee) out, the Packers opened the game with a starting line left-to-right of Chad Clifton, Daryn Colledge, Jason Spitz, Tony Moll and Mark Tauscher. After the Rodgers-to-Greg Jennings touchdown on the first play from scrimmage, Moll stayed in at right guard but Orrin Thompson came in at left tackle, Allen Barbre at left guard, Junius Coston at center and Breno Giacomini at right tackle.

Giacomini, a rookie fifth-round pick battling for one of the final roster spots on the line, gave up back-to-back sack-fumble plays to Jevon Kearse (against Flynn) and Jacob Ford (against Brohm). Coston left with a knee injury and did not return.

Extra points

Inactive for the game were Wells, Sitton, A.J. Hawk (chest), safety Atari Bigby (ankle), cornerbacks Charles Woodson (rest, knee) and Al Harris (rest, back), defensive tackle Ryan Pickett (hamstring), wide receiver James Jones (knee) and defensive end Kabeer Gbaja-Biamila (knee). .... Tyrone Culver, trying to make the team as the final safety, had an interception. ... Wisconsin native Bill Carolo, who doesn't do Packers games during the regular season, was the referee. ... Olympic gold-medal swimmer Garrett Weber-Gale of Milwaukee was at the game. ... Ex-Packers backup Ingle Martin saw action at quarterback for the Titans, while former Middleton athlete Casey Cramer had a special teams tackle. ... Although Will Blackmon, Tramon Williams and Jordy Nelson appear to be the three top kickoff returners, rookie Pat Lee (36-yard return, 28.3-yard average) may be in the mix now, too.
