"That is a little bit of a concern," Schiano said.
Wright's injury comes on the heels of reports that he faces a potential four-game suspension for Adderall use, which violates the NFL's policy on performance-enhancing drugs.
"Per the league guidelines, I really can't discuss it, and neither can Eric," Schiano said.
A reporter asked Schiano if he would be disappointed to see another of his players penalized after cornerback Aqib Talib was hit with a four-game suspension for using the same substance. Schiano declined to answer.
If Wright misses Sunday's game against the Oakland Raiders -- because of injury or the league hammer -- a combination of Brandon McDonald and Myron Lewis will be asked to step up for the Bucs. Schiano also expressed confidence in Leonard Johnson, but losing your top two cover men isn't easy to rebound from in the NFL.
