Tindall moved to strengthen his defence after Justin Roberts was sent-off for retaliation in the 1-0 FA Cup Fourth Qualifying Round replay win at Hitchin Town on Tuesday.
With the ex-Nottingham Forest defender suspended for three games and Ashley Vickers, Trevor Challis, Kyle Critchell and Simon Weatherstone all injured, Young is expected to go straight into the starting XI for tonight's Blue Square Premier clash against Aldershot Town at the Wessex Stadium (7.45pm).
The 34-year-old, who has only made four League One appearances for the Cherries this season, has also been given permission to play in Weymouth's FA Cup First Round Proper tie at Eastbourne Borough on November 10.
Tindall said: "It is not very often that a club like Weymouth can sign a player of the quality and experience of Neil Young.
"He is a leader and two out of the last three seasons he has been Bournemouth's player of the year.
"I actually wanted to sign him in the summer but Bournemouth offered him a contract that we could not compete with.
"One of the conditions for him coming down was that he would be able to play in the FA Cup for us and Bournemouth have agreed to that which is great.
"I am sure a lot Bournemouth fans will be disappointed to see him come down here because he is a very popular player there but I am just delighted to have him here."
Sido Jombarti remains a long-term absentee but Stuart Beavon is likely to play a prominent role at some point after returning to the first-team squad as an unused substitute at Hitchin.
Tindall said: "Trevor and Sido are both still injured while Simon and Kyle have just returned to light training and are both at the same stage in their recoveries. I am expecting those two to start full training next week.
"As for Stuart Beavon, he was on the bench on Tuesday but had not trained for a few days before that because of illness. He will play a part tonight whether it is in the starting XI or the 16."
Aldershot's leading scorer John Grant returned to action as a late substitute on Tuesday after recovering from tendonitis. The 26-year-old has so far netted nine goals in 13 outings and Tindall is well aware of the threat he could pose.
He said: "The table does not lie. Aldershot are a very good side, they have got a lot of pace about them and they have been scoring a lot of goals but so have we.
"It promises to be a very exciting game but rest assured we will be looking for the three points. We have been in good form lately and we want to keep it going, and we see tonight's game as one we can win."
Aldershot coach Martin Kuhl could be in hot water with the Football Association after being sent from the dug-out during Tuesday's game at Crawley.
Red Devils' boss Steve Evans has alleged that Kuhl punched his assistant Paul Raynor and has vowed to take the matter further.Reporter: Adam Summers
