On Wednesday, the former "Blossom" star injured her thumb after her white volvo collided with another vehicle.
L.A. police department Sgt. Monte Houze confirmed to People.com yesterday, "From what I was told, there was a lot of blood at the scene. (Bialik suffered) a severe injury to her left thumb."
Following her release from the hospital the actress was photographed with her right hand in a cast. She headed back to work merely 24 hours after the incident and was welcomed with open arms by her co-stars.
She tweeted, "How much do I get love and support from the big band (sic) cast and crew? I went to work today... doing ok. Grateful. And tired."
