TAMPA — Cornerback Jamel Dean made his second start Sunday against the Jaguars but it didn’t last long. The third-round pick from Auburn played only seven snaps before suffering a bruised shoulder. “We’ll know more probably this afternoon,'' coach Bruce Arians said Monday. “Jamel looked pretty sore.”The Bucs also are concerned about starting right guard Alex Cappa, who suffered a right elbow injury during Tampa Bay’s 28-11 win in Jacksonville. Cappa missed two games with a broken left arm this season.“I don’t know what (Cappa’s injury) is yet,” Arians said. "He probably played a quarter with it and didn’t say anything. I wish he had said something because he was struggling a little bit.''Cappa was replaced by veteran Earl Watford at right guard. The Bucs mixed up their secondary following Dean’s injury, playing veteran cornerback Ryan Smith on occasion.One day after Devin White followed his first career interception with a fumble recovery and return 14 yards for a touchdown, it’s hard not to declare him the Bucs’ best rookie.Sean Murphy-Bunting also had a game-sealing interception in the end zone.“It’s huge. Once you do it, you know you can. Devin had the sacks last week. The interception this week,” Arians said. "The touchdown is huge for him and his growth. Sean, it’s a second time for him."I see Mike Edwards playing faster and faster.''But none of those players may be the Bucs’ best rookie this season, Arians said. That distinction could go to kicker Matt Gay, who is 23 of 26 on field-goal attempts this season, making 88 percent of his kicks."Somebody just me what rookie you think has probably had the most impact? Of course, I start reeling off (players) and forgot about Matt Gay,'' Arians said. "He’s probably had the best impactful impact of all of them.''
