Stallions running back Mike Pringle, coming off a season-high 201 yards rushing and career-high four touchdowns last week, will miss tonight's game against Birmingham with a tender left hamstring that has bothered him all week.
Robert Drummond will start in Pringle's place.
"After the first set of plays [at yesterday's practice], I decided it would be best if I took myself out," said Pringle, who practiced for the first time this week on Thursday. "I don't even like to miss practice, but I have to be smart about this. I probably could go, but it's not worth the risk. We still have six games left."
Pringle, who broke the Canadian Football League season rushing record with 1,972 yards last year, currently leads the CFL with 1,232.
"It was his decision," Baltimore coach Don Matthews said. "He could have played, but we would be taking a chance on losing him for four or five weeks if he reinjured it. We feel good about Drummond."
Drummond, who mainly has split time with fullback Peter Tuipulotu this season, replaced an injured Pringle in last year's playoff opener against Toronto and rushed for 111 yards in Baltimore's 34-15 victory.
This season, Drummond has rushed 24 times for 141 yards and caught 19 passes for 184 yards.
