Angels manager Mike Scioscia said Kendrick is considered day-to-day and will travel with the team to Seattle for the start of a critical three-game series.
"I don't really know what it is. It's kind of strange," said Kendrick, whose 15-game hitting streak ended after he flied out in his only at-bat Thursday. "It's just a pain on the inside of the knee. I was running on the field, it kind of gave out, and all I can tell you is it just didn't feel good."
Kendrick said he had a similar pain in that knee about a month ago but was able to play through it. He intends to go through some pregame drills Friday in Seattle to see how it responds before getting any tests on the knee.
"I played through it last time. It wasn't as sharp of a pain. I just kind of stretched it out," Kendrick said. "I wasn't going to say anything this time either but it was just a little sharper than I'd like. Once I tried to put pressure on it, it just didn't want to hold up. Hopefully this is nothing major and I can just miss today."
Kendrick is hitting .324 (77-for-238) since June 9.
