Martinez was in the lineup at DH but can't play the field without risking re-injury. That wasn't an issue on Thursday, since Alex Avila was going to catch Justin Verlander anyway, but at some point this weekend in Baltimore, manager Jim Leyland would probably like to give Avila a day off.
"We're in a little bind," Leyland said. "Victor can't catch right now. That's also a day-to-day thing."
If the situation remains into next week, the Tigers might be forced to call up a catcher to back up Avila. But the only other catcher on the 40-man roster is Omir Santos, who's working his way back from a thigh injury that has sidelined him for the past month.
Santos went 0-for-2 on Thursday in a rehab start for the Tigers' Gulf Coast League team. He's scheduled to catch twice more there, Leyland said, and at that point he could rejoin Triple-A Toledo, or be an option for the Tigers if they need a second catcher.
