Jason Bay continues to rest with a concussion, but the Mets are no closer to knowing the severity of his injuries.

The Mets may get a chance to visit with the left fielder today, when it's possible he will be at Citi Field for the first time since sustaining the concussion Friday night. Bay was examined by a specialist yesterday and will be evaluated again today.

"I don't think we know how serious it is yet, and may not know for at least a few days," general manager Sandy Alderson said before the Mets' 5-0 win over the Orioles.
