Kilmarnock suffered deadline-day disappointment when they failed in bids to sign Airdrie forward Allan Russell and Dundee full-back Paul Dixon.
Dundee rejected the Scottish Premier League club's approach for highly-rated 21-year-old Dixon.
But 27-year-old Russell could yet move to Rugby Park in the summer.
Killie manager Jim Jefferies told BBC Sport: "The timescale was just too tight, but we are hoping now to sign him on a pre-contract agreement."
Russell was at Rugby Park attempting to conclude his move minutes before the midnight deadline.
Jefferies had been looking for a replacement after having sold Colin Nish to Scottish Premier League rivals Hibernian.
And Russell had impressed the Rugby Park management team while they were scouting the Second Division outfit ahead of Scottish Cup tie between the sides.
Dundee United were also interested in Russell and could still pursue the player who started his career with Hamilton before heading for St Mirren, Macclesfield, Mansfield, Forest Green and Partick Thistle then Airdrie last summer.
Killie could also attempt to sign Dixon during the coming close season.
Assistant manager Billy Brown said: "It's something we are still hoping to fix up."
Meanwhile, striker Baz Savage, who has been released by Brighton, is due to arrive at Rugby Park for a trial.
