Fernando Alonso's crash in testing ahead of the Indianapolis 500 has lumbered the double world champion with a "significant setback" in his attempts to secure the 'Triple Crown' in this weekend's race. Alonso wrecked his #66 McLaren on Wednesday, and was unable to get on-track throughout the following day as repairs were carried out.
Alonso has placed huge stock in his attempt to match Graham Hill's unique feat by winning at the Brickyard, as well as the Le Mans 24 Hours and Monaco GP.
Having impressed in his ultimately unsuccessful Indy debut two years ago, all eyes will be on the Spaniard once again, but he has been impacted by the wreck on Wednesday.
"It's definitely slow going," said McLaren CEO Zak Brown.
"It's been a lot of work. We're just trying to get it done right, put some extra TLC in it and make sure it is ready to go.
