Nashville, TN (SportsNetwork.com) - Tennessee Titans quarterback Zach Mettenberger's shoulder injury is not believed to be serious, head coach Ken Whisenhunt told reporters on Monday.

The Titans are hopeful he'll be able to play Sunday against the Giants.

Mettenberger suffered a Grade 1 sprain of his AC joint following a big hit from J.J. Watt in the third quarter of Sunday's 45-21 loss to the Texans.

Jake Locker, who was replaced by Mettenberger as the Titans' starter last month, came on in relief, and his first pass was intercepted. Locker was picked off twice and tossed for 91 yards and a touchdown on 6-of-12 throws.

Mettenberger threw for 184 yards with a touchdown and an interception before leaving.

Whisenhunt also provided an update on wide receiver Justin Hunter, who suffered a lacerated spleen Sunday and was taken to an area hospital. Whisenhunt said he should be released in the next day or two, but didn't comment on Hunter's status going forward.
