"That being the case, we'll lose him for the year," coach Jeff Fisher said Tuesday.
Calico has played in one game this season. He missed the first three games after spraining both knees and tearing cartilage in his left knee Aug. 30 in a preseason game at Dallas. Fisher said the team doctor noticed fraying on the ACL when he repaired the cartilage then.
But Calico's knee appeared stable enough that he played in Tennessee's 38-17 loss at San Diego on Oct. 3 only to fall down after trying to make a cut in the flat. He has two catches for 13 yards, far short of the offensive output the Titans expected from him this season.
Even if Dr. James Andrews only repairs the medial meniscus, Calico still would be out up to 10 weeks. The Titans have 12 weeks left in the regular season.

Olson undergoes MRI: Right guard Benji Olson had an MRI Tuesday on his right groin muscle. Fisher said Olson has a strain that could keep a player out between one and six weeks, but he expects Olson to be a game-time decision for Sunday's contest with Houston because of his ability to play with pain.
Dallas Cowboys: Scrambling again for cornerback help after absorbing a second season-ending knee injury to a young player at that key position, the Cowboys on Tuesday reached into the Baltimore Ravens practice squad again for help, signing rookie Lance Frazier to the active roster.
The move came after an MRI examination confirmed that Cowboys rookie cornerback Bruce Thornton sustained a torn anterior cruciate ligament in his right knee during last Sunday's loss to the New York. A fourth-round draft choice who dressed for his first outing of the season last weekend, Thornton was placed on injured reserve Tuesday and will undergo surgery within the next week or so.
The former University of Georgia standout, a very promising cover defender, is expected to be rehabilitated in time for training camp next summer.
The addition of Frazier marks the second time in a week that coach Bill Parcells has turned to the Ravens practice squad to address an injury. Last week, the Cowboys signed rookie tight end Brett Pierce from the Ravens, after veteran tight end Dan Campbell sustained a knee injury that also ended his season prematurely. Despite limited practice time with his new team, Pierce actually played in Sunday's game against the Giants.

New Orleans Saints: Veteran Fred
McAfee signed up for his third stint with the team Tuesday.
McAfee, who made the Pro Bowl in 2002 for his special teams contributions, also played in New Orleans from 1991-93 and 2000-2003. He had 15 tackles, nine solo, on special teams last season for the Saints in 14 games.
Hoag, who played at Minneapolis Washburn High School and
Division III Gustavus Adolphus College in St. Peter, was on the
team's practice squad since the beginning of the season. He'll get
a chance to replace wide receiver Keenan Howry as a punt and
kickoff returner. Howry injured his shoulder in Sunday's game at
Houston and might have to be placed on injured reserve.
The Vikings released Yates to make room for Hoag. Yates is expected to be added to the practice squad if he's not picked up by another team. Tight end J.P. Foschi was also released from the practice squad on Tuesday.
Hoag was "Mr. Irrelevant" in the 2003 draft -- chosen with the last pick by the Oakland Raiders.
