With so much abuse raining down from the stands, it must be difficult for players to keep a lid on their emotions sometimes. Especially goalkeepers, given that they are often so close to opposition fans when tending the net.
But with age comes experience, or so you would think, as most become so hardened to the slurs screamed at the from the sidelines that they are able to shut them out completely.
Only instances where something particularly vile is yelled do these seasoned veterans react, and unfortunately for Tim Howard, he's now finding that out the hard way.
The former Manchester United stopper is now on the books of MLS side Colorado Rapids, where he is seeing out the remainder of his career, but this week he's been handed a three-match ban for a verbal altercation with a fan.
Howard's side took on Sporting Kansas City recently (and lost 3-1) but the result was overshadowed by the 38-year-old's run in with SKC's British-born forward Dom Dwyer.
The two exchanged a heated debate at the final whistle after the result hadn't gone Howard's way, but now a new video has come to light showing something far more sinister.
Footage has been posted to Twitter by a fan that was in the stands, with the video appearing to who the USA international telling a supporter to 'go f*** your mother'.
The statement was met with a derisive cheer from those nearby and the MLS disciplinary commission has since confirmed that he will miss the next three games with both incidents counting towards their decision.
See the footage for yourself below, but be warned that it contains adverse language.
The ban will now put the ex-Everton 'keeper out of action until May 5, when the Rapids will take on Canadian side Vancouver Whitecaps.
This means he will miss the clashes with Real Slat lake this weekend, before meetings with Atlanta United and Orlando City.
He will be a huge miss for Colorado, who are currently sat in 11th place (out of 12) in the Western Conference. Having only played four games to everyone else's six, they have won one, drawn one and lost two, leaving their hopes of making the playoffs hanging in the balance already.
