Tough news for Sabres forward Kyle Okposo after the Sabres game on Sunday against the Chicago Blackhawks. The veteran forward was diagnosed with a concussion and will be out indefinitely.

According to WGRZ, this is Okposo's fourth concussion in just over two years.

The harsh reality in contact sports is the risk players run playing with a history of concussions. Since Okposo has a history, the Sabres are likely to be extremely cautious moving forward in getting him back on the ice.

The Sabres next play at home on Tuesday night against the Minnesota Wild.
