Bristol City produced a spirited performance to earn an FA Cup replay against Nottingham Forest after a goalless fourth-round stalemate at Ashton Gate.
Tommy Conway missed a great chance for the Championship hosts when his half volley from Albania midfielder Anis Mehmeti's cross flew wide.
The two sides will try again at the City Ground on the week beginning 5 February.
Having knocked out West Ham in the third round, City were looking to eliminate more than one top-flight opponent in the same FA Cup campaign for the first time since 1919-20.
Liam Manning's side looked dangerous going forward, particularly after half-time, but were unable to force Forest keeper Matt Turner into a serious save.
Back to the City Ground
Nuno Espirito Santo has his first clean sheet at the seventh attempt as Forest boss after a dogged defensive performance by his side.
Bristol City were roared on by a raucous crowd and carved out nine attempts over the 90 minutes - but none on target.
After Conway's earlier miss, Cameron Pring had another great chance for an 85th-minute winner but fired into the side-netting.
In a tense finale, Wood - who had a spell on loan at Bristol City in 2012 - mis-timed a header when the New Zealand forward looked set to score and Hudson-Odoi also found the side-netting late on.
Forest needed a replay and extra time to see off League One Blackpool in the third round and will now need to win another replay if they are to advance to round five.
As for Bristol City, they remain unbeaten after three matches against Premier League sides - two against West Ham and one against Forest - in this season's FA Cup, despite sitting 13th in the Championship.
Manning will hope his players can take belief from those performances to help improve their league position.
