They posted a poor first half showing, having gone behind early on but recovered sufficiently to earn a share of the spoils.
Rovers failed to deal with an early free-kick that was sent to the back-post and Connor O'Riordan bundled in after slipshod defending from the visitors.
Shortly after Rovers were indebted to goalkeeper Ted Sharman-Lowe after a terrific stop to deny Kane Hemmings' close-range header.
The rest of the half saw Grant McCann's men toil to no avail and another couple of smart saves from Sharman-Lowe ensured it was only a 1-0 deficit at the interval.
The second half didn't see a vast improvement and McCann made four substitutions at once, just after the hour mark. And not long after they finally drew level. A Luke Molyneux corner was met by a booming header from Owen Bailey to restore parity.
Crewe had the better of the chances to pinch all the points before Rovers saw a penalty appeal involving sub Joe Sbarra waved away.
Here's how we rated the Rovers players:
9. Luke Molyneux 6
Was bright in the early exchanges. Went more central second half and made more of an impact, before providing the assist for Bailey's goal from a corner. Booked. Photo: Bruce Rollinson/AHPIX LTD
10. Jordan Gibson 4
One of many who under-performed. One moment that summed up Rovers' first half when he ran into space down the flank only to trip up comically. Hooked at the break. Photo: Bruce Rollinson/AHPIX LTD
11. Rob Street 5
Fed off relative scraps in his 63 minutes on the pitch. Bent a shot around a post first half but that was as good as it got. Photo: Bruce Rollinson/AHPIX LTD
12. Joe Ironside 5
Led the line well after his half-time introduction and was a battering ram, as per. Photo: Howard Roe/AHPIX LTD
