PITTSFORD -- Jordan Matthews' first practice with the Buffalo Bills will be his last for awhile.
The Buffalo Bills announced Monday that the newly acquired wide receiver was found to have a "chip fracture" in his sternum and is considered week-to-week.
General Manager Brandon Beane told The Buffalo News Matthews is expected to be recovered in time for the Sept. 10 regular-season opener against the New York Jets. Beane said the team is hopeful the receiver would be available at least in time for the final preseason game against the Detroit Lions on Aug. 31, but would not take any unnecessary risks to get him on the field in the preseason.
A team spokesman had revealed that Matthews was being evaluated for a chest injury after Sunday's workout, which he finished, at its St. John Fisher training camp.
Beane said that, in reviewing video of the practice Sunday night, it was apparent the injury occurred when Matthews collided with cornerback Shareece Wright within the first 15 minutes of practice. Wright left Sunday's session early with an injury to his right thumb.
Matthews joined the Bills Friday in a trade with the Philadelphia Eagles. The Bills sent cornerback Ronald Darby to Philadelphia, and also received a third-round draft pick.
Matthews is considered a leading candidate to fill one of the Bills' top three receiving spots. In another trade Friday, the club sent No. 1 wideout Sammy Watkins to the Los Angeles Rams.
