Silva said the Cubs medical staff has been treating him with ice and ultrasound. The Cubs starter said he will throw a side session on Tuesday and prepare for his regular start on Friday.
In other news on the Cubs' health front:
• Jeff Gray continued to work his way back into the Cubs' bullpen mix while recovering from a severe groin strain. Gray said he is shooting for Wednesday as the target for his first Cactus League appearance of the spring.
• Aramis Ramirez said he hopes to get back into Cactus League play on Wednesday. The third baseman has missed over a week with a strained right triceps. Ramirez said he will practice throwing Monday in preparation for Wednesday. The team's trainers have been treating him with ultrasound on the arm.
• Andres Blanco was able to play on Sunday for the first time after missing two weeks with a strained knee. Blanco is out of minor league options, so if he does not make the 25-man roster, he will become subject to a waiver claim by any of the other 29 teams. If Blanco clears waivers, the Cubs could re-sign him to a minor-league contract.
