The restart after the 31st-minute goal was delayed after the incident this afternoon but Mr Bryan, who appeared to have been hit on the back of the neck, was fit to continue.
A fan was led out of the stadium by police and stewards soon after. The Football Association, which has issued warnings on flares this season, said the incident was 'unacceptable' and will investigate.
A West Midlands Police spokesman said on Twitter tonight: ‘Police have arrested two men after a lit flare was thrown on the pitch during the Villa v Spurs game - the flare hit a linesman.
‘The two men aged 25 and 47 were arrested following the incident at Villa Park. Fortunately the linesman wasn't injured.’  Spurs won the game 2-0, with Roberto Soldado scoring the second goal.

'We will await the match officials' report and will be speaking to the clubs. Such incidents highlight the dangers of pyrotechnics being used in a football stadium.'
TalkSport presenter Ian Abrahams said on Twitter: 'Smoke bombs and flares may be banned but idiots are still getting them into grounds, so stewards are not doing their job.'
Policing Minister Damian Green warned football fans in August that those who were smuggling flares into matches were putting other supporters’ lives at risk.
In May, a 15-year-old boy suffered lung damage from a smoke bomb thrown during Villa's 2-2 draw at Wigan Athletic, while two women aged 22 and 24 also required medical attention.
Three months earlier a 14-year-old boy was killed by a flare thrown by fans during a South American Libertadores Cup match between San Jose and Corinthians in Orouro, Bolivia.
