T.J. Clemmings didn't have time to dwell on what might be wrong with Phil Loadholt.
His veteran mentor had just limped to the sideline and coaches were barking at Clemmings to replace him. The rookie buckled up his helmet, jogged out to the huddle then took over at right tackle for the rest of Saturday night's opening series.
It wasn't until the drive ended that he learned the severity of Loadholt's injury.
"When I came back to the sideline and found out he wasn't able to go, I was like, 'All right, you've got to step up,' " Clemmings said Monday.
With Loadholt lost for the season because of the torn left Achilles' tendon he suffered against the Tampa Bay Buccaneers, the Vikings will turn to Clemmings, a promising prospect who received Division I scholarship offers for basketball and has played offensive line for only three years.
The Vikings say that before Loadholt's injury they were pleased with how Clemmings was coming along. But now they have four weeks to ramp up his development to get him as ready as he can be to start against the San Francisco 49ers in Week 1.
And to think, just seven years ago Clemmings was pulling on shoulder pads for the first time.
He was a standout big man on the hardwood with offers to play hoops at Rutgers, Providence and Seton Hall. He wanted to play football, too, but his mother, Fay, wouldn't let him. Before his junior year of high school, Clemmings asked for permission yet again.
