14 minutes: After an anonymous start, Rangers captain Ferguson gets on the ball for the first time in open play and surges forward, only to play a poor pass.
17: First sight of Ferguson as an attacking threat. Sprints into the Dundee United penalty area to meet a cross by Steven Davis from the right but Garry Kenneth heads the ball out for a corner.
20: Goes close to opening the scoring. Kirk Broadfoot's cross from the right is dummied by Lee McCulloch and Ferguson's firm shot on the turn is palmed away by Lukasz Zaluska.
33: Another chance, but this time Ferguson's shot is less convincing. His flicked effort loops over the United goal.
43: Loose left-footed 20-yard shot from Ferguson goes high and wide as Rangers fail to cancel out Noel Hunt's strike before half-time.
50: Ferguson's cross from the right causes United's defence to panic but the lurking Darcheville is eventually crowded out.
66: Turns quickly and shoots from 15 yards but his effort is charged down.
67: Ferguson again takes a shot from inside the penalty area but scuffs the effort and United hurry the ball clear.
93: Called on to play a deeper role following the tactical reshuffle in the second half, Ferguson attempts to make a surge into the United penalty area but is dispossessed and United break, leading to their second goal.
115: Ferguson's free-kick from the left is cleared at the expense of a corner as Rangers, with the score at 2-2, seek a winner.
