Michael Appleton’s men were excellent for the most part as they came seconds away from surprising the former league leaders.
But Oliver Norwood’s heart-breaking 98th minute goal meant the Seasiders were forced to settle for a point.
Here’s how Blackpool’s players rated at Bramall Lane:
1. Chris Maxwell - 9/10
Made a string of stunning saves late on before the heartbreaking late equaliser, which he was clearly fouled for. Photo: CameraSport - Andrew Kearns
2. Callum Connolly - 7/10
Had plenty of defending to do, although he was supported well by Shayne Lavery. Threw his body on the lines. Photo: CameraSport - Andrew Kearns
3. Marvn Ekpiteta - 4/10
He was having a shaky game even before his needless red card. Silly challenge to make when on a booking. Photo: CameraSport - Andrew Kearns
4. Jordan Thorniley - 7/10
Steady as ever once again. Didn’t really notice him, which is certainly a compliment. Made two or three big blocks. Photo: CameraSport - Andrew Kearns
5. Dom Thompson - 3/10
At fault for the first goal and then put his side under real pressure late on with his moment of stupidity for the red card. Needs time out of the side. Photo: CameraSport - Andrew Kearns
6. Liam Bridcutt - 8/10
A real calming influence among all the chaos. Getting 75 minutes under his belt will be crucial for him going forward. Photo: CameraSport - Andrew Kearns
