KNOXVILLE, Tenn. (AP) — Tennessee offensive tackle Trey Smith knows he may need time to get back to peak form after a health scare forced him to miss spring practice.He's just grateful to be back on the field after blood clots in his lungs put his football future at risk."I was blessed and fortunate to be out there, period," he said Monday.Smith wasn't cleared for contact until late August and had only eight more practices from that point until the start of the season. Smith acknowledges he's still "getting a lot of rust out" as he gets ready for Saturday's home opener with East Tennessee State (1-0).The Volunteers (0-1) are counting on Smith to anchor an offensive line that took some lumps in a season-opening 40-14 loss to No. 17 West Virginia.
