Kyrie Irving's concussion suffered against the Miami Heat earlier in the week has had the rookie star listed as 'day to day' for the next while, and it looks like the injury has gotten the better of the 19 year old. Boyer Reed tweeted Friday morning that Irving will be missing both of Cleveland's weekend games with concussion issues.

The Cavs' two games this weekend are against the Milwaukee Bucks Friday evening and the Philadelphia 76ers on Saturday. The Cavs were able to work without their young star against the Los Angeles Clippers when Ramon Sessions stepped up into the point guard role in a big way, with 23 points and 13 assists. They'll need similar performances to keep coming from Sessions if they want to keep their hopes up in a tight spot for the lower playoff spots in the Eastern conference.

The Cavs announced the signing of Ben Uzoh on Friday to mitigate a bit of the damage.
