The Canadian Football League announced Wednesday that Lewis’ tweet was unacceptable and was in violation of the league's social media policy.
On Monday, the Stampeder slotback tweeted, "I just bought OJ's gloves on eBay. Now all I need is a white girl named Nicole." He also added a hashtag — #maybealittletofar.
According to the team and league, he did go too far.
Head coach John Hufnagel has asked all Stamps players not to tweet until the off-season.
On Wednesday, Lewis admitted he crossed the line.
"I try to use my comedic rights and I guess I went a little too far," said Lewis.
"The people that know me, know I try to be funny all the time and don't mean any malice, any harm to anybody."
When asked if he regretted the tweet, Lewis replied, "Do I regret it? I regret getting money taken out of my pocket, I regret saying it, but I can't take it back."
On Thursday, Lewis also issued an apology and said he will be donating his Western final game cheque to a women's emergency shelter.
The league's social media policy states that posts are public and should be treated as if the player was being interviewed.
"If a player, team employee or league employee uses social media ... in a manner that may bring the CFL into disrepute, including posts that condone harassment, discrimination or violence, are obscene or sexually explicit, or divulge proprietary information or disparage the league, teams, officials, players, employees or fans, they will be subject to discipline from the Commissioner's Office," states the policy.
Earlier this season, the B.C. Lions Khalif Mitchell was fined by the CFL and suspended by his team after he made a disparaging reference to people of Chinese descent.
It's the second straight week the Stamps have had to deal with off-field distractions.
Last Wednesday, a Calgary radio host was suspended for saying he hoped the Saskatchewan Roughriders plane would crash and four people die.
Calgary quarterback Drew Tate also felt it necessary to release a statement regarding some concerning comments he made at halftime during the Western semifinal.
During a halftime interview on Sunday, Tate told a TSN interviewer that he didn't remember the helmet-to-helmet hit he took in the first half.
