The Bucs have made plenty of changes to the offensive line the past few weeks, but have yet to make a change at left guard. They don’t think they’ll have to. The Bucs are growing confident LG Carl Nicks will return to action this year after being sidelined much of the past two seasons with a foot injury and a MRSA staph infection. “He’s been rehabbing and things look promising, so we are crossing our fingers and hoping for the best,’’ Bucs general manager Jason Licht said Tuesday. Nicks signed a five-year, $47.5 million free-agent contract with the Bucs in 2012, but has played in only nine games since. A left foot injury ended Nicks’ 2012 season after seven games and a MRSA infection on the same foot ended his 2013 season after just two games. The Bucs are hopeful Nicks will be back on the field when their 2014 offseason workout program begins in April. “We’re gathering all the information we have with the doctors that we’ve sent him to, and we’re hoping for that,’’ Licht said. “We’ll see.’’ Changing of the guard Nicks is attempting to return to a line that will look drastically different than the one he played on a year ago. The Bucs have a new left tackle in Anthony Collins, a new center in Evan Dietrich-Smith and eventually will have a new right guard to replace Davin Joseph, who was recently released. The Bucs have yet to settle on a starter at right guard, and there is a chance he is not even on the roster yet.
