Sergio Romo is one of the most important cogs in the San Francisco Giants' bullpen, but unfortunately may be missing some time after it was released that he hasn't been available the last two games due to a sublexed patella, or an unstable knee in non-medical terminology.

Skipper Bruce bochy discussed the injury before Wednesday's game against the Arizona Diamondbacks:

"He did it two games ago stretching down below, doing his normal routine," Bochy said. "So he has not been available to us for two games. He did have it checked out. An MRI confirmed the subluxed patella in the right knee."

Even though Romo is technically available to pitch on Wednesday, Bochy noted he'd like to keep him on the pine to rest up before giving the knee a test, likely making him available Friday after the off day if he is healed up and ready to go.

Romo has been outstanding again this year, owning a 2-0 record and 0.60 ERA in 14.2 IP this season, including a 20/5 K/BB ratio this year.
