Skip Bayless Questions LeBron James' Injury In Heated Exchange W/ Sha |

Skip Bayless and Shannon Sharpe went at it Tuesday morning on their FS1 show "Undisputed" ... after Skip insinuated LeBron James is lying about his injury.

Of course, it was reported Monday that James might miss substantial time with a right foot injury ... but Skip isn't buying he's hurt, questioning the legitimacy of LeBron's injury.

Bayless told Sharpe he hasn't seen any difference in Bron since the Lakers superstar turned 38 in December, and said he appeared to be fine during Sunday's game vs. Dallas.

Sharpe, however, took issue with Skip's comments, especially since LBJ said he "heard it pop" against the Mavs, prompting a war of words between the two hosts.

“Why is it when someone says something is wrong with LeBron James you either say it’s not that serious or he’s lying?” Sharpe asked. "But you’ve never called into question when Tom Brady said anything."

James, meanwhile, posted a pic of his right foot on Instagram Monday ... with the caption, "Fkn Sucks!!!! "

Skip is known for being critical of LeBron ... but Sharpe was having none of his latest theory, which figures to have NBA fans like Shannon up in arms.
