The New Orleans Saints are hopeful the hamstring injury suffered by CB Randall Gay in Sunday’s 38-7 win over the Bucs is not severe.

New Orleans has signed cornerback Chris McAlister, a former Pro Bowler with Baltimore, with CB Tracy Porter out four to six weeks with an MCL injury, according to a league source.

The Ravens released cornerback Chris McAlister, freeing up $8 million against the salary cap to use to try to re-sign linebackers Ray Lewis and Terrell Suggs, according to a team official.

While the Steelers’ injury problems are well documented — Willie Parker, LaMarr Woodley, Ben Roethlisberger — Baltimore has injury problems of its own. In the same week, the Ravens will place two defensive backs on injured reserve, ending their season.
