B.C. Lions lineman Khalif Mitchell has been fined an undisclosed amount by the CFL for posting a message containing a racial slur on his Twitter account.

Not long after, the team said he won't play Friday against the Edmonton Eskimos.

While tweeting about Tuesday's U.S. presidential debate, Mitchell posted a message with a term that is derogatory towards Chinese.

He later apologized for using the word, saying he didn't know it was offensive.

The league said Mitchell broke the guidelines of its social media policy, which states that players publishing online postings "that may bring the CFL into disrepute, including posts that condone harassment, discrimination or violence" are subject to discipline from the league commissioner.

Lions CEO Dennis Skulsky announced in a statement that Mitchell would not return to the lineup this week.

"While Khalif has missed the previous three games due to injury and was slated to return this week, a joint decision has been made between VP of football operations Wally Buono, head coach Mike Benevides and I to remove him from the starting lineup," Skulsky said.

This decision is a response to Khalif’s inappropriate comments made on his Twitter feed this morning and despite his public expression of remorse, we believe this is the best course of action for our organization at this time."

Skulsky said it was particularly disappointing given the team's diverse fanbase in B.C.

It's not the first time Mitchell has been in trouble with the league this season. Earlier he served a two-game suspension for hyperextending the elbow of  Eskimos offensive lineman Simeon Rottier.
