Steve Summers and Russell Goldstein registered for Redbridge.
Let down at the last minute by two players, RJC were down to 11 players and had 10 players for the last 30 minutes, with the challenge coming from Lions and a rejuvenated opposition given they had put fresh legs on at half-time.
Redbridge were leading 2-0 at half time, via goals from Goldstein and the "outstanding Summers who was teaching the Lions defence a few things about technique and hold up play".
The second half was a half of backs-to-the-wall job for RJC. Lions brought on the returning Jamie Jackson, whom Jon Jacobs described as "a giant of a player who made a real difference to the game with his driving play".
An early goal reduced the arrears but with seconds remaining and it looking like a famous RJC victory on the cards, Lions stole an equaliser at the death from a close-range move.
Redbridge boss Jon Jacobs told JC Sport: "Today was a battling performance and I felt we fully deserved our point against a young and talented Lions side.
"Steve Summers' forward play in the first half deserves a special mention as it was a class apart from the rest whilst Adam Hakimi played his first 90 minutes for a long time at the back and looked really comfortable."
