A point was no good for either side as League Two promotion rivals Cheltenham and Oxford played out a goalless draw.
Marlon Pack went closest for the hosts, but his fierce free-kick came back off the woodwork, while Darryl Duffy's header was tipped over by Ryan Clarke.
Ben Burgess volleyed wide on his Robins debut, while James Constable headed over at the other end.
Luke Summerfield went close with two efforts for the home side, while the U's struggled to make an impression.
Cheltenham remain in sixth place on 65 points, while Oxford sit three points back with a game in hand in seventh.
VIEWS FROM THE DRESSING ROOM
Cheltenham manager Mark Yates told BBC Radio Gloucestershire:
"We've come off the back of four defeats and sometimes you need a small step before you take a big one.
"We've got seven games left and we're a point nearer where we want to be. We deserved three points. We didn't take our chances but the bottom is I'm delighted with the effort, the desire was there and if we play like that we'll be alright.
"Steve (MacLean) hasn't played much for a month and Ben (Burgess) tired towards the end, but it's a start for us. We had lots of chances and I'm not going to criticise players for missing chances. The crowd stuck with us even though it was 0-0. It's a small step and one we needed.
"We can only look after ourselves. We're still going for 21 points and the players deserve a massive pat on the back. There have been a few doubters - not on performances like that."
Oxford United manager Chris Wilder told BBC Radio Oxford:
"We rode our luck at times, we had to defend, but towards the end we came on strong so it was a real end-to-end game.
"It was always going to be like that. I didn't take any notice of current form, they're a good team with good players and a good manager. When we roll into town with 1,700 (supporters) it's always going to raise their desire and determination to get a result.
"It wasn't a great performance from us but it was a real gritty one. We're not under-estimating what a good point it is."
