The Texas Rangers may have lost Matt Harrison and Martin Perez for the remainder of the season.
Harrison left Tuesday's game with a stiff back after 1 2/3 innings and has been diagnosed with severe nerve irritation in his lower back. He will need spinal fusion surgery to eliminate the discomfort, which could sideline him for the rest of the season.
Perez has a partial tear of the ulnar collateral ligament in his left elbow. He could return in 10 to 12 weeks if he rehabs the injury successfully, but Tommy John surgery is a possibility.
Harrison signed a five-year, $55 million deal in January 2013 after winning 18 games. Since then, he's 1-2 with a 5.79 ERA.
Perez signed a four-year, $12.5 million deal in November with team options through 2020.
