Sanju Samson's Rajasthan Royals will face a stern test of character as they look to arrest a shocking slide in a do-or-die IPL Eliminator against an in-form Royal Challengers Bengaluru, here on Wednesday.

The Royals, at one stage, had looked set for a top-place finish in the league stage before a string of four defeats and a washout in the last game against KKR resulted in Sanju Samson's side finishing third behind Sunrisers Hyderabad.

On the other hand, RCB have sensationally fought their way back from the brink of elimination. After losing seven of their first eight games this season, the team led by Faf du Plessis hit a dream run and finally knocked out defending champions Chennai Super Kings a few nights ago to seal a playoffs berth.

If Rajasthan Royals are coming off four losses and a rained-off game, RCB have notched up six consecutive wins to sound a warning to their rivals that they mean business in the playoffs.

RR, the 2008 IPL winners, suddenly find themselves as the underdogs, when a couple of weeks ago they were red-hot favourites.

When on song, Rajasthan Royals have shown they are unbeatable, but the last four games have exposed frailties in their batting and bowling.

The exit of Jos Buttler has taken a lot of firepower out of their batting and a lot will depend on Yashasvi Jaiswal (348 runs), skipper Samson (504) and Riyan Parag (531) to halt the slide.

Samson and Parag will once again be expected to deliver the goods for RR, with England's Tom Kohler-Cadmore expected to partner Jaiswal in what seems like a frail opening pair going by form and experience.

Shimron Hetmyer is expected to be available for the contest giving Rajasthan solidity in the lower order, which has not made a big contribution with the bat this season.

RRs strong bowling line-up could come in handy given the venue for the Eliminator has not been a batting paradise like the other grounds, where shorter boundaries and docile tracks have made the bowlers' job tougher.

The 200-run mark has been breached only twice in 12 innings this season at the Narendra Modi Stadium, which means the team having a disciplined bowling attack and a strong batting line-up is more likely to win here.

On the other hand, RCB's Virat Kohli continues to be the highest run-getter this season with 708 runs from 14 matches and could make the difference in the contest.

After initial struggles, RCB skipper Faf du Plessis has also found form with the bat to forge a dominating partnership at the top with Kohli, while Rajat Patidar (five half-centuries this season) has also given solidity at the top.

RCB have not been impacted much by the exit of England's Will Jacks, while veteran Dinesh Karthik is firing on all cylinders with a strike rate in excess of 195 lower down the order.

In their last match, left-arm seamer Yash Dayal turned around his fortunes to dish out a splendid final over against CSK to deny them a win and lead RCB into the playoffs.

For a bowler who was devastated after conceding five consecutive sixes in an over last year, Dayal has proved his mettle this year.
