Liverpool striker Luis Suarez was handed a 10-match ban by the English Football Association on Wednesday after the Uruguayan was given a charge of violent conduct earlier in the week.
Suarez was handed the suspension after biting the arm of Chelsea defender Branislav Ivanovic in the second half of last Sunday's 2-2 draw at Anfield.
"A three-person independent regulatory commission today upheld the FA's claim that a suspension of three matches was clearly insufficient and the player will serve a further seven first-team matches in addition to the standard three. The suspension begins with immediate effect," a statement from the FA read.
Suarez has until noon on Friday to appeal the suspension and his club expressed disappointment in the outcome of the situation.
"Both the club and player are shocked and disappointed at the severity of today's Independent Regulatory Commission decision," Liverpool managing director Ian Ayre said. "We await the written reasons tomorrow before making any further comment."
Suarez will miss Liverpool's final four matches of the season as well as the first six domestic matches next term, potentially ruling the Uruguayan attacker out until October.
Suarez has apologized to Ivanovic, who suffered a bruise from the bite, and Liverpool acted quickly to quell the latest controversy surrounding their striker by imposing a fine which is being donated to the Hillsborough families' support group.
