07:29 AM ET 01.01 | Quite a bit hangs in the balance of Kyrie Irving's forthcoming MRI exam. The Cleveland Cavaliers and Los Angeles Lakers continued discussions Tuesday on a deal centered around former teammates Andrew Bynum and Pau Gasol, but sources close to the situation told ESPN.com that the outcome of [Irving's MRI] is likely to have a big impact on how the talks proceed from here. ... If Irving is out for a substantial length of time, it's believed that the Cavaliers' appetite to take on additional salary in pursuit of a playoff push would inevitably be diminished. The Lakers, meanwhile, remained firm Tuesday in their insistence on acquiring additional assets from the Cavaliers in addition to Bynum's cap-friendly contract in exchange for the four-time All-Star from Spain.
