The MRI taken Monday on Locker's right wrist revealed no structural damage, Jim Wyatt of The Tennessean reports. Locker was diagnosed with a strain and continues to experience soreness with the wrist, which could limit his involvement in practice this week. If the Titans determine Locker is unfit to play in Week 4, Charlie Whitehurst would seem to have a clear path to the starting gig, with fellow backup Zach Mettenberger expected to miss practice time this week following a death in his family.

Locker underwent an MRI on his right wrist Monday, NFL.com reports. Per Jim Wyatt of the Tennessean, coach Ken Whisenhunt said he's unsure about Locker's availability for Sunday's game against the Colts. In the event that Locker is unable to play in Week 4, the Titans would to turn to Charlie Whitehurst as their starting QB.

Locker completed 17-of-34 passes for 185 yards, but he was picked off twice and fumbled twice (both were recovered), in a 33-7 loss to the Bengals on Sunday. On the positive side, Locker racked up 50 rushing yards on six carries, highlighted by a 29-yard run. Unfortunately, it was a fairly ugly game overall, with Locker failing to throw a touchdown for the first time this season. He'll look to bounce back in Week 4 against a Colts defense that is ranked 28th against the pass this season.

Locker had a mediocre performance in Sunday's 26-10 loss to Dallas, throwing for 234 yards with one touchdown and a pair of interceptions. Locker didn't lead Tennessee to any points in the first half, and his lone touchdown came on an incredible individual effort by Delanie Walker, who scored from 61 yards away. For those that streamed Locker against a below average Cowboys defense, it was certainly a major disappointment. He still remains an intriguing option, albeit an inconsistent one, with lots of weapons, and as his rushing ability.

Locker completed 22-of-33 passes for 266 yards and two touchdowns, while also adding 14 rushing yards on six carries Sunday against the Chiefs. Locker connected with eight different receivers, throwing touchdowns to wide receiver Kendall Wright and tight end Delanie Walker. While he did take four sacks, he didn't turn the ball over and he led the Titans to a solid 26-10 win at Arrowhead Stadium. Up next is the home-opener against the Cowboys, who allowed 201 passing yards and two passing touchdowns to the 49ers on Sunday.

Locker completed 12-of-17 passes for 188 yards and a touchdown in Saturday's preseason game against the Falcons. He gained 12 yards on his only carry but did take a pair of sacks. Locker played well for a second straight week, though he was once again facing a shaky NFC South defense. Still, his preseason performance has been encouraging, and the Titans have an intriguing trio of wide receivers in Kendall Wright, Nate Washington and Justin Hunter.

Locker looked sharp in Friday's preseason loss to New Orleans, completing 8-of-11 passes for 75 yards and a touchdown. He added seven yards on one run attempt. Locker didn't waste any time, responding to New Orleans' opening touchdown by leading the Titans on a seven-play, 62-yard charge down the field on the team's first drive. Locker showed good touch on the scoring play, throwing a fade to the back of the endzone to Justin Hunter, and overall looked poised at the helm of the first-team offense.

Locker completed 1-of-2 passes for five yards and added two yards on two carries in Tennessee's preseason opener against Green Bay on Saturday. Locker's quiet night had more to do with torrential downpour than anything else. The Titans focused on the running game as a result, though it should be noted that Locker did have trouble securing a few snaps in the bad weather. Still, the fact Locker got through an entire quarter without injury should do wonders for his confidence going forward.

The Tennessean believes new coach Ken Whisenhunt is grooming Jake Locker as a pocket passer. Locker's strong mobility is an asset, but Whisenhunt isn't going to drastically change the system that made stars out of statuesque quarterbacks Ben Roethlisberger, Kurt Warner and Philip Rivers. It's a risky proposition. Locker has been notoriously inaccurate dating back to his college days, and has also been skittish while progressing through reads in the pocket. We won't be targeting him as our QB2.

Jake Locker (Lisfranc surgery) is participating in this week's minicamp. Locker also participated in all 10 OTAs, getting back on the field a little earlier than the Titans expected. It's great news for a quarterback that needs all the work he can get and is learning a new offense. Now in his fourth season, Locker must settle down in the pocket and improve on his career completion percentage of 57.2.
