Kevin Doyle's penalty shoot-out strike helped Colorado Rapids defeat Robbie Keane's LA Galaxy in the MLS Conference semi-finals.

A penalty shoot-out decided the match after the tie finished 1-1 on aggregate, after Shkelzen Gashi scored for Colorado in the 36th minute and it finished 1-0 after extra-time.

Doyle scored from the spot in the 3-1 shoot-out win in the match which may have been Steven Gerrard's last ever game, as his Galaxy side exit the play-offs.

Gerrard scored in the penalty shoot-out which was the only successful Galaxy spot-kick in a game which saw Keane start on the bench. The former Ireland captain came on after 61 minutes.

Former Tottenham man Giovanni dos Santos missed a penalty for the Galaxy, while Ashley Cole and Jeff Larentowicz saw their attempts saved by former Everton keeper Tim Howard.

The loss ends the Galaxy's season, and with Gerrard's contract due to expire in December - and with little suggestion of an extension - the 36-year-old could be set for retirement.

Last month an Instagram message from the former Liverpool favourite sparked speculation that he was calling it a day - although the tribute to Galaxy supporters had been sent to mark their fan appreciation night.

Even so, Liverpool boss Jurgen Klopp later said Gerrard was "always welcome" at the club as he was linked with a possible coaching role.
