Smith (groin/back) was a limited participant in Wednesday's practice.
Smith sat out Week 10 due to the groin injury, but he returned to action last weekend against Dallas, hauling in both of his targets for 23 yards while playing 52 percent of offensive snaps. The second-year tight end now also appears to be dealing with a back issue, but as long as he can continue practicing on at least a limited basis Thursday and Friday, he should have a fair chance of suiting up Sunday versus Carolina.
