Locker, who was listed as a limited participant in Friday's practice, will be listed as questionable for Sunday's game against the Colts, the Tennessean reports. "It was encouraging. We got to see Jake do a little bit," coach Ken Whisenhunt noted Friday. "But that's what we anticipated. Hopefully (he'll) progress more and we'll obviously see what we can do tomorrow. That will determine a lot of what we decide on." The report notes that Whisenhunt plans to assess Locker's condition again Saturday before making a determination on the QB's status for Sunday, with a game-time decision potentially looming here in advance of the team's 1:00 ET kickoff. For his part, Jim Wyatt of the Tennessean is skeptical that Locker will be able to play this weekend. In any case, Charlie Whitehurst would be in line to draw the start at QB for the Titans on Sunday against the Colts in the event that Locker is unable to go.
